Of course, this Grand Seiko Sport SBGE305 Caliber 9R 20th Anniversary Limited Edition has something to do with where Seiko’s are produced. This time the color of the dial is inspired by the morning glow of the Hotaka mountain range in summer.
It’s a dark-ish red you can see when the sun comes up, not only in the Shinshu region of central Japan of course. This red looks like the red on this Grand Seiko Sport SBGC275 Caliber 9R 20th Anniversary Limited Edition, although the dial of that model has a multilayer coating for extra shimmering effect.
GMT and date and power reserve
The main function is the second time zone, indicated by the GMT hand. While the watch is running you can just set the local hour hand independently forward or backward. Which makes it very easy to operate.
At the 4 o’clock position is a date window, at the 8:30 position is a power reserve indicator. The black ceramic bezel has a 24-hour scale, at the flange of the dial is a second one. This has two colors to indicate day or night at the second time zone.
The Grand Seiko Sport SBGE305 Caliber 9R 20th Anniversary Limited Edition has a power reserve of 72 hours
